“…was observed in the cohort of poultry (37 positive samples on 217, 17.0%). However, this frequency was much lower than the previously reported infection rates based on the in vitro cultivation detection method, reaching 82.5% in a group of 57 chickens sampled in the Ismailia governorate in Egypt [36], and 30.5% from a light microscopy examination of 200 intestinal samples of chickens collected in the Assiut governorate located in central Egypt [38]. Such variations in the prevalence between these surveys can be explained by the different geographical locations and lifestyles of the animals that, in some cases, may facilitate the circulation of the parasite.…”

“…A still-too-limited set of transmission studies, including animal samples, was carried out in different regions, such as Africa [1], although this region is considered to be at high risk of infection from this parasite. In North Africa, in particular in Egypt, only four surveys have been conducted to date, focusing on various animal groups, including poultry, bovid and pets [35][36][37][38]. However, these surveys included a restricted number of animal samples and used conventional methods of detection for Blastocystis sp., such as direct light microscopy and short-term xenic in vitro cultures, which are known to likely underestimate the prevalence of the parasite compared to the end-point or quantitative real-time PCR (qPCR) assays [39,40].…”

Prevalence, Subtype Distribution and Zoonotic Significance of Blastocystis sp. Isolates from Poultry, Cattle and Pets in Northern Egypt

Blastocystis sp. is a widespread enteric protozoan that frequently infects human and animal groups. Despite its burden and zoonotic potential worldwide, epidemiological investigations remain limited in animal groups that come in contact with humans. Therefore, the largest survey ever conducted in North Africa was performed in Egypt with the aim to investigate the prevalence and subtype (ST) distribution of Blastocystis sp. in animals. For this purpose, a total of 889 fecal specimens were collected from chickens (217), cattle (373), dogs (144) and cats (155) from six governorates of northern Egypt. These specimens were then screened for the presence of Blastocystis sp. using a quantitative real-time PCR, followed by subtyping the isolates. The overall prevalence of Blastocystis sp. reached 9.2% (82/889), with the highest infection rates reported in chickens (17.0%) and domestic cattle (11.0%), highlighting an active circulation of the parasite in both animal groups. In contrast, the low prevalence in cats (2.6%) and the absence of the parasite in dogs suggested that pets are not natural hosts of Blastocystis sp. ST10 and ST14 were largely predominant in cattle, confirming that both STs represented cattle-adapted STs. The report of one ST3 and one ST4 isolate in this animal group could be explained by an accidental zoonosis from humans to animals. All but one of the subtyped isolates in poultry belonged to ST7, which was considered as an avian ST. The presence of a remaining isolate of ST14 likely reflected a transient infection from contact between birds and cattle feces. The same environmental contamination was also likely the source of the ST14 infection in three of the four positive cats, with the remaining animals infected by ST3 as the result of human-to-animal transmission. These occurrences and subtyping data, combined with those previously collected in the Egyptian population, implies that poultry could play a significant role as reservoir for zoonotic transmission, which would not be the case for cattle and pets.

“…In Egypt, the prevalence of Salmonella in poultry at the farm level was reported in several studies, where it ranges from 2.5% in layers to 11.3% in broilers [ 23 , 24 , 25 ]. Few studies reported the prevalence of Blastocystis in poultry at the farm level, where it reached, respectively, 24 and 69.8% in two surveys conducted in Egypt [ 26 , 27 ].…”

Poultry and poultry meat are considered the most important sources of human campylobacteriosis and salmonellosis. However, data about the occurrence of Campylobacter and Salmonella concomitantly with intestinal protozoa such as Blastocystis sp. in poultry remain very scarce. Therefore, this study aimed to investigate the presence and possible interactions between these three microorganisms in fecal samples from 214 chickens collected either on farms or from live bird markets in Egypt. The results obtained showed that Campylobacter spp., Salmonella spp., and Blastocystis sp. were present in 91.6% (196/214), 44.4% (95/214), and 18.2% (39/214) of tested samples, respectively, highlighting an active circulation of these microorganisms. Moreover, a significant positive correlation was reported between the occurrence of Campylobacter spp. and Blastocystis sp. together with a significant negative correlation between Blastocystis sp. and Salmonella spp. This study confirms the association reported previously between Blastocystis sp. and Campylobacter spp. while disclosing an association between Blastocystis sp. and Salmonella spp.; it also highlights the need to improve studies on the interactions between bacteria and eukaryotes in the gut microbiota of poultry.
